I 57 ABSTRACT 15 Claims, No Drawings PHOTOGRAPHIC ELEMENTS CONTAININGBALLASTED RESORCINOLS This invention relates to photographic elementsand processes of forming images in photographic elements. In one aspect,this invention relates to photographic elements containing a ballastedresorcinol compound. In another aspect, this invention relates tophotographic elements which have improved resistance to environmentaleffects, background stain, etc. In another aspect, this inventionrelates to improved image transfer systems.

It is known in the art to add various scavenger compounds tophotographic elements to retard certain reactions of the left overdevelopers, by-products of the development reactions, atmosphericcontaminants and the like. Certain hydroxybenzene compounds 'are shownin US. Pat. Nos. 2,336,327, 2,403,721, 2,728,659 and 2,360,290 toprevent color stain in photographic elements. U.S. Pat. Nos. 3,459,548,3,287,126 and 3,482,971 discloses scavengers for oxidized developingagents. Polymeric compounds containing appended polyhydroxybenzenegroups, such as hydroquinone groups, have been suggested for use tocontrol stain in US. Pat. Nos. 2,710,801 and 2,816,028. However, many ofthe additives used as scavengers acted as a redox agent, especially inthe case of scavenging oxidized developers, and reduced the oxidizeddeveloping agent. Also, many of the socalled antistain agents weresilver halide developers which could enter in competing reactions withcolor developing agents. Therefore, improved additives are desirable,especially in color systems such as image transfer systems.

We have now found that certain ballasted resorcinol compounds can beused in photographic elements to improve the image quality and agingproperties of the image record. Generally, the photographic elements ofthis invention comprise a'compound of the formula:

, (inn) .pentadecylenecarbonamido resorcinol and the like.

The photographic elements containing the above ballasted resorcinolcompounds have improved image I properties; apparently, these compoundsare very effective as'scavengers for by-products or excess ingredithus,can be put in any desired layer of the photo-' graphic element sincethey will not compete with the developing agents or reactivate oxidizeddeveloping agents.

The improvements in image stability with the compounds of this.invention are believed to offer a definite advance in the art; theclosely related monohydroxy compounds and the polyh ydroxy compoundswherein the hydroxy groups are not in 1,3-position do not appear tooffer-the same improvements when used at similar weight percentageconcentrations. Moreover, the present ballasted resorcinol compounds cangenerally be incorporated in hydrophilic colloid layers with organicsolvents having low boiling points, such as acetone, ethyl acetate,etc.; thus thinner coatings can be used compared to couplers requiringlarge amounts of high-boiling-point organic solvents to achieve uniformdispersion.

In one preferred embodiment, the ballasted resorcinols are present in aphotographic element which is processed with a color developing agent.

In another embodiment, the ballasted resorcinols are present inphotographic elements in combination with color-forming couplers toscavenge oxidized color developer which does not react with the colorcoupler.

effectively any excess color developer by forming a col.-

orless' reaction product, thereby eliminating the need for a pigmentedmasking layer.

In another embodiment, the scavengers of this inven-' tion are used incombinationwith a timing means so that development in the photosensitiveelement is substantially complete before the scavenger is effectivelyassociated with the development medium.

Inone preferred embodiment, the scavengers of this invention are used incombination with color transfer units, and preferably those transferunits wherein the dye image-receiving layer is integral with thephotosensitive element itself or is .provided on a separate support entsin silver halide development reactions, especially color developmentreactions, When -color developers such as aromaticprimary amines areused in the development reaction, the ballasted resorcinols appear toscavenge the excess developer which may provide discoloration uponaerial oxidation or extraneous oxidato be superposed on thephotosensitive element after exposure thereof. In-oneembodiment,-elements of this type comprise a film unit which is adaptedto be processecl by passing the unit between a pair of juxtaposedpressure-applying members, such as would be found in a camera designedfor in-camera processing, comprising:' 0' I i a. a photosensitiveelement comprising a support having thereon at least one and preferablythree photosensitive silver halide emulsion layers, each silver halideemulsion layer having associated therewith a dye 3 image-providingmaterial comprising a nondiffusible coupler capable of reacting withoxidized aromatic primary amino color developing agent to produce adiffusible dye;

b. a dye image-receiving layer; and

c. a rupturable container containing an alkaline processing compositionand which is adapted to be positioned during processing of the film unitso that a compressive force applied to the container by thepressureapplying members will effect a discharge of the containerscontents within the film unit; the above film unit containing anaromatic primary amino color developing agent, preferably in therupturable container, and a ballasted resorcinol in a polymeric binderwhich is capable of reacting with unused aromatic primary amino colordeveloping agent to form a colorless or substantially colorless reactionproduct.

The ballasted resorcinols of this invention generally require the use ofan organic solvent to achieve a uniform dispersion in a hydrophiliccolloid layerof a photographic element. However, low-boiling-pointorganic solvents having a boiling point of less than 100 C., such asacetone, ethyl acetate and the like, are very effective in achievinguniform dispersions of the present scavengers. While high-boiling-pointorganic solvents, such as coupler solvents, can be used to obtaindispersions, they are generally not employed since it is usually morepractical to use low-boiling-point solvents. The ballasted resorcinolscan generally be incorporated in photographic elements by any of thetechniques employed in the art for dispersing materials of this typewhich have very marginal water solubility. When they are dispersed inhydrophilic colloid layers they can be dispersed by techniques known fordispersing coupler solvents or by means employing the low-boiling-pointsolvents to obtain uniform dispersions. The ballasted resorcinols can beemployed in any concentration useful for the intended purpose. However,generally lower weight percentages of the present ballasted resorcinolsare required to provide an effective scavenging as compared to othercompounds used in the prior art for this purpose. We have found thatconcentrations of from 1 mg. per square foot to about 500 mg. per squarefoot, and preferably from about5 mg. to 100 mg. per square foot, can beused for most purposes.

The ballasted resorcinols'can generally be located in any layer of aphotographic element (including imagereceiving. sheets). The ballastedresorcinols can generally be incorporated in all vehicles used incoating photographic elements including, for example, proteins,cellulose derivatives, polysaccharides, synthetic polymeric substancesand the like. In certain embodiments, the ballasted resorcinols areincorporated in hydrophilic, water-permeable colloids, or syntheticpolymeric compounds such as dispersed vinyl compounds such as in latexform and particularly those which'increase the dimensional stability ofthe photographic materials. Suitable synthetic polymers include thosedescribed, for example, in US. Pat. Nos. 3,142,568 by Nottorf issuedJuly 28, 1964; 3,193,386 by White issued July 6, 1965; 3,062,674; byHouck et al. issued Nov. 6, 1962; 3,220,844 by Houck et al. issued Nov.30, 1965; 3,287,289 by Ream et al. issued Nov. 22, 1966; and 3,41 1,91 lby Dykstra issued Nov. 19, 1968. Particularly effective are thosewater-insoluble polymers of alkyl acrylates and methacrylates, acrylicacid, sulfoalkyl acrylates or methacrylates, those which havecross-linking sites which facilitate hardening or curing described inSmith, US. Pat. No. 3,488,708 issued Jan. 6, 1970, and those havingrecurring sulfobetaine units as described in Dykstra, Canadian Pat. No.774,054.

The term nondiffusing used herein has the meaning commonly applied tothe term in color photography and denotes materials which for allpractical purposes do not migrate or wander through organic colloidlayers, such as gelatin, comprising the sensitive elements of theinvention. The same meaning is to be attached to the term immobile.

The term diffusible has the converse meaning and denotes materialshaving the property of diffusing effectively through the colloid layersof the photographic elements, and generally refers to materials whichcan migrate to any layer of the element during aqueous treatment. Mobilehas the same meaning.

The scavengers of this invention can be used in any photographic elementwhere it is desired to immobilize or scavenge an unwanted reactionproduct or contaminant. In one embodiment, they are used effectively inblack-and-white or color photographic products to scavenge unwantedaldehydes. in another embodiment, the ballasted resorcinols areespecially useful in color photographic elements which employ a colorsilver halide developer during processing.

The term color developer is understood to refer to that class ofcompounds known in the art as color silver halide developers, andgenerally refers to silver halide developers which in their oxidizedform will couple with a color-forming coupler. Generally, thesedevelopers are aryl compounds having at least one NH group thereon.

In a highly preferred embodiment of our invention, the ballastedresorcinols are used in image transfer systems including those transfersystems wherein the image-receiving layer remains integral with thephotosensitive emulsion, as well as those where the imagereceiving layeris separated from the photosensitive layers.

In one embodiment of our invention wherein the image-receiving elementis separate from the photosensitive element, the novel dyeimage-receiving element comprises a support having thereon the followinglayers:

a. a scavenger layer comprising a ballasted resorcinol in a polymericbinder and b. a dye image-receiving layer.

A timing layer, described hereinafter, can also be em- I ployed in theinvention between the scavenging layer and the dye image-receiving layerwhich functions to delay the rate of diffusion of aromatic primary aminocolor developing agent into the scavenging layer. The timing layer,therefore, ensures the efficient use of the aromatic primary amino colordeveloping agent in the photosensitive element prior to scavengingaction by the ballasted resorcinol. A pH-lowering material, de-

' scribed hereinafter, can also be employed in the dye image-receivingelement to increase the stability of the transferred image. Although notrequired, a lightreflective layer comprising a white pigment in abinder, described hereinafter, can also be employed in the dyeimage-receiving element, if desired. The light-reflective layer can belocated underneath the dye imagereceiving layer or can be combined withthe timing layer if one is employed.

pods attached to the reception sheet or photosensitive element that canbe readily ruptured when development is desired as described, forexample, in US. Pat. Nos. 2,559,643, 2,647,049, 2,661,293, 2,698,244,2,698,798 and 2,774,668.

During the development phase of a color diffusion transfer processaccording to our invention,-the image dyes formed in the respectiveblue-, greenand redsensitive silver halide emulsion layers diffuse outof the photosensitive element through the viscous developer compositionand into the dye image-receiving layer, e.g., into the dyeimage-receiving element described above, where the dyes are mordanted toform the transferred image. The timing layer, if one is present,prevents the diffusion of color developer into the scavenger layer forthe time necessary to ensure the efficient use of the aromatic primaryamino color developing agent in the photosensitive element. Uponseparation, it is believed that-the unused aromatic primary amino colordeveloping agent diffuses into the scavenger layer where the developermolecules can react with the ballasted resorcinol under alkalineconditions of development to form a colorless or substantially colorlessreaction product. Regardlessof themechanism involved, a marked decreasein the yellowish-brown stain caused by the presence of unused colordeveloping agent in color development diffusion transfer image-receiving elements is observed upon utilizing a scavenger layercomprising a ballasted resorcinol dispersed in a suitable binder,preferably in the imagereceiving element.

In another embodiment of our invention, the scavenger layer can belocated in an integral film unit wherein the dye image-receiving layeris located'integral with the photosensitive element between the supportand the lowermost photosensitive silver halide emulsion layer. Suchintegral receiver-negative photosensitive elements are described incopending U.S. application Ser. No. 115,459 of Barr, Bush and Thomasfiled Feb. 16, 1971, now abandoned. In such an embodiment, the supportfor the photosensitive element is transparent and is coated with the dyeimage-receiving layer, a substantially opaque, light-reflective layer,e.g., TiO a scavenger layer comprising a ballasted resorcinol dispersedin a suitable binder, and the various layers forming the color-formingunits. After exposure of the photosensitive element, a rupturablecontainer containing an alkaline processing composition and an opaqueprocess sheet are brought into superposed position. Pressure-applyingmembers in a camera rupture the container and spread processingcomposition over the'photosensitive element as the film unit iswithdrawn from the camera. The processing composition develops theexposed silver halide layers and dye images are formed as a function ofdevelopment which diffuse to the image-receiving layer to provide apositive, rightreading image which is viewed through the transparentsupport on the opaque reflecting layer background. It is believed thatpositioning of the scavenger layer between the color-formingphotosensitive units and the image-receiving layer in the integralreceiver-negative film system prevents the diffusion of unused colordeveloper into the image-receiving layer. If desired, an auxiliaryscavengerlayer comprising the scavenging materials described herein canbe located on the opaque process sheet. For further detailsconcerningthis particular integral film unit, its preparation and use, referenceis made to the above-mentioned U.S. ap-

plication Ser. No. 115,459 of Barr, Bush and Thomas filed Feb. 16, 1971,which is incorporated herein by reference.

Another embodiment of integral receiver-negative photosensitive systemsin which our invention can be employed is described in U.S. Ser. No. 115,552 of Cole filed Feb. 16, 1971, now abandoned. In such anembodiment, the support for the color diffusion transfer system istransparent and is coated with the imagereceiving layer, a substantiallyopaque, light-reflective layer, e.g., ,TiO a scavenger layer comprisinga ballasted resorcinol dispersed in a suitable binder, and then thevarious layers forming the color-forming units and a top transparentsheet. A rupturable container containing an alkaline processingcomposition and an opacifier is positioned adjacent to the top layer andsheet. The film unit is placed in a camera, exposed through the toptransparent sheet and then passed between a pair of pressure-applyingmembers in the camera as it is being removed therefrom. Thepressureapplying members rupture the container and spread processingcomposition and opacifier over the negative portion of the film 'unit torender it lightfinsensitive. The processing composition develops theexposed silver halide layers and dye images are formed as a result ofdevelopment which diffuse to the image-receiving layer to provide apositive, right-reading image which is viewed through the transparentsupport on the opaque reflecting layer background. Any unused aromaticprimary amino color developing agent which may difiuse in the directionof the image-receiving layer is immobilized by the ballasted resorcinolpresent in the scavenger layer. Any undesirable products fomied in thescavenger layer are masked from the viewer by the opaquelight-reflective layer. For further details concerning this particularintegral film unit, its preparation and use, reference is made to theabovementioned Cole U.S. application Ser No. 1 15,552 filed Feb. 16,1971, which is incorporated herein by reference.

' Very good results are obtained when the ballasted resorcinols are usedin the photographic film units where there is associated with eachsilver halide emulsion layer in the photosensitive element a dyeimageproviding material comprising a nondiffusible coupler whichproduces a diffusable dye on reaction with oxidized aromatic primaryamino color developing agent in an alkaline processing composition.

Typical preferred image transfer systems of this type disclosed in U.S.Pat. Nos. 3,227,551, 2,559,643, 3,443,940, 3,443,939 and the like.

lnert timing or spacer layers referred to above can be employed inphotographic elements of our invention. Generally, they are employedbetween the scavenger layer and a dye image-receiving layer which timesor controls the scavenging reaction as a function of the rate at whichalkali diffuses through the inert spacer layer. Examples of such timinglayers include gelatin, polyvinyl alcohol or any of those disclosed inU.S. Pat. No. 3,455,686. The timing layer is also effective inevening'out the various reaction rates over a wide range oftemperatures, e.g., premature pH reduction is prevented when imbibitionis effected at temperatures above room temperature, for example, at 95to 100 F. The timing layer is usually about 0.1 to about 0.7 mil inthickness. Especially good results are obtained when the timing layercomprises a hydrolyzable polymer or a mixture of such polymers which areslowly hydrolyzed by the processing composition. Examples of suchhydrolyzable polymers include polyvinyl acetate, polyamides, celluloseesters, etc.

The invention can be further illustrated by the following examples.

EXAMPLE l-A:

In the evaluation of the effectiveness of the scavengers of thisinvention, an image transfer system is constructed as itemized below: 1

ELEMENT A:

1. support;

2. layer containing 1 l mg./ft. of gelatin, mg./ft. of tricresylphosphate, 87 mg. of Coupler No. 1 of U.S. Pat. No. 2,474,293 and asilver halide emulsion at 87 mg. silver/ftF;

3. layer containing 100 mg./ft. gelatin, 2O mg./ft. Coupler No. l ofU.S. Pat. No. 2,474,293 and 10 mg./ft. of tricresyl phosphate;

4. layer containing gelatin at 107 mg./ft. the scavengers of Tables 1and 2 and NiS at 4.8 mg./ft. Processing Solution:

5.1 g. of 4-amino-3-methoxy-N-ethyl-N-B-hydroxyethyl-aniline, 0.8 g. ofpiperidinohexosereductone, 5.0 g. of hypo and 11.8 g. of NaOH per literof water;

ELEMENT B:

1. support;

2. layer containing 454 mg. of gelatin/ft.

3. layer containing 208 mg. of gelatin/ftP, 173 mg./ft. of Coupler No. lof U.S. Pat. No. 2,474,293, 86.5 mg./ft. of tricresyl phosphate and 2.4mg./ft. of Pd nuclei.

The light-sensitive element A is exposed through the support of elementA to a graduateddensity test object and presoaked for 5 seconds at atemperature of 70 F. in the processing solution. The receiver B ispresoaked for seconds in the same solution and subsequently brought intocontact with the light-sensitive element. Both are passed between rubberrollers and left in contact for 3 minutes. Upon separation and drying ofthe two components, the receiver is analyzed for silver in the areascorresponding to minimum exposure of the negative. Cyan dye densitydeveloped in the receiver and the level of silver found in the receiverare both indications of the efficiency of consumption of oxidizeddeveloper by the nucleated layer (layer 3) of the negative. The lowerthe silver and dye densities in the receiving element, the better theefficiency of the oxidized developer scavenger contained in layer 3 ofelement A. Maximum efficiency of this layer should promote completephysical development of all complexed silver reacting in the nucleilayer and should consume all oxidized developer generated in the layer.

The following data illustate the effectiveness of a resorcinolderivative according to this invention in scavenging oxidized developercompared to the effectiveness of color couplers, as well as theeffectiveness of a variety of other ballasted monohydroxy and dihydr'oxybenzenes.

The following compounds are evaluated by incorporating them in thenuclei layer (layer 4) of the lightsensitive element A and by processingthe exposed element in the described manner. Concentrations of theincorporated compounds andthe effectiveness of the compounds asscavengers for oxidized developers are shown in Tables 1 and 2.
